摘要：

The frequency dependence of the dielectric response deduced from the analysis of infrared reflection spectra of the BaTaO2N perovskite is reported. The results are compared with those of barium titanate and discussed. It is concluded that the substitution of one nitrogen for oxygen - together with replacement of Ti-+IV by Ta-+V to ensure the proper charge balance - appears to cancel the possibility offered by some oxidic perovskites to observe very high dielectric constants since here no soft mode behaviour is found.
